invention are expounded below in conjunction with the
implementations and accompanying drawings.

disposed around the first base 1, the end face of one end of the
first shielding frame 5 contacts with a first external PCB, and the
end, close to the first external PCB, of the first shielding frame
5 is in the shape of a complete and gapless ring.
[0020] From the above description, the invention has the following
beneficial effects: the first shielding frame 5 disposed around the
first base 1 is complete and gapless and can realize 360.degree.
omnidirectional and dead zone-free shielding, so that the
anti-interference capacity of the radio frequency connector is
effectively improved, and the electrical performance of the radio
frequency connector is improved, accordingly.
[0021] Furthermore, at least one part of the end face of the first
shielding frame 5 is welded to the first external PCB.
[0022] From the above description, the first shielding frame 5 is
welded to the first external PCB, so that the first shielding frame
5 can be grounded steadily, thus guaranteeing the shielding
performance of the radio frequency connector.
[0023] Furthermore, the radio frequency connector further comprises
a second base 2 which is plugged and matched with the first base 1,
wherein a second shielding frame 7 is disposed around the second
base body 2, and at least one part of the first shielding frame 5
is located in the second shielding frame 7.
[0024] Furthermore, the end face of one end of the second shielding
frame 7 contacts with a second external PCB, and the end, close to
the second external PCB, of the second shielding frame 7 is in the
shape of a complete and gapless ring.
[0025] From the above description, the second shielding frame 7
disposed around the second base 2 is complete and gapless and can
realize 360.degree. omnidirectional and dead zone-free shielding of
a second terminal 4 on the second base 2, so that the
anti-interference performance and electrical performance of the
radio frequency connector are further improved.
[0026] Furthermore, at least one part of the end face of the second
shielding frame 7 is welded to the second external PCB.
[0027] From the above description, the second shielding frame 7 is
welded to the second external PCB, so that the second shielding
frame 7 can be grounded steadily, thus guaranteeing the shielding
performance of the radio frequency connector.
[0028] Furthermore, a first terminal 3 is disposed on the first
base 1, and the first shielding frame 5 has convex encapsulation
parts 6 for covering weld legs of the first terminal 3. From the
above description, the convex encapsulation parts 6 can decrease
the size of the first base 1 on the premise of ensuring
omnidirectional shielding of the first terminal 3, so that the
installation space of the radio frequency connector is reduced, and
the radio frequency connector can adapt to more installation
environments.
[0029] Furthermore, gaps are reserved between the inner walls of
the convex encapsulation parts 6 and the weld legs of the first
terminal 3.
Embodiment 1
[0030] Referring to FIG. 1 to FIG. 4, Embodiment 1 of the invention
is as follows: referring to FIG. 1 and FIG. 2, a radio frequency
connector comprises a first base 1 and a second base 2, wherein a
first terminal 3 is disposed on the first base 1, a second terminal
4 plugged with the first terminal 3 is disposed on the second base
2, and the first base 1 is plugged and matched with the second base
2 through the cooperation of the first terminal and the second
terminal.
[0031] In this embodiment, the first base 1 is a female base, and
the first terminal 3 is a female terminal; and correspondingly, the
second base 2 is a male base, and the second terminal 4 is a male
terminal. Or, in other embodiments, the first base 1 may be a male
base. A female connector end constituted by the first base 1 and a
first shielding frame 5 may be an integral structure formed by
inserts through an injection molding process, or an assembled
structure formed through later assembly and connection. A male
connector end constituted by the second base 2 and a second
shielding frame 7 is formed in a similar way.
[0032] Referring to FIG. 1 to FIG. 3, a first shielding frame 5 is
disposed around the first base 1, the end face of one end of the
first shielding frame 5 contacts with a first external PCB, and the
end, close to the first external PCB, of the first shielding frame
5 is in the shape of a complete and gapless ring. The end face of
one end of the first shielding frame 5 contacts with the first
external PCB, so that a seam between the first shielding frame 5
and the first external PCB is avoided, and the risk of signal
interference and leakage is drastically lowered. Ideally, the
height of the first shielding frame 5 is equal to that of the first
base 1. In fact, under the influence of various factors such as
machining conditions and operating environments, the height of the
first shielding frame 5 may be slightly smaller than that of the
first base 1. Optionally, the bottom surface of the first shielding
frame 5 is coplanar with the bottom surfaces of weld legs of the
first terminal 3.
[0033] Furthermore, at least one part of the end face of the first
shielding frame 5 is welded to the first external PCB, so that the
first shielding frame 5 is made conductive with the first external
PCB, and the connection stability of the female end and the first
external PCB is improved. Because the first shielding frame 5 is in
the shape of a complete ring, a conduction region between the first
shielding frame 5 and the first external PCB should be also in the
shape of a complete ring theoretically. In fact, due to the
constraints of the installation environment or other factors, the
conduction region between the first shielding frame 1 and the first
external PCB may not be a complete ring, that is, the end face,
close to the first external PCB, of the first shielding frame 5 is
conductive with a local part of the first external PCB.
[0034] As shown in FIG. 1, a second shielding frame 7 is disposed
around the second base 2, at least one part of the first shielding
frame 5 is located in the second shielding frame 7, the end face of
one end of the second shielding frame 7 contacts with a second
external PCB, and the end, close to the second external PCB, of the
second shielding frame 7 is in the shape of a complete and gapless
ring. The second shielding frame 7 can realize 360.degree.
omnidirectional and dead zone-free shielding of the second terminal
4.
[0035] Furthermore, at least one part of the end face of the second
shielding frame 7 is welded to the second external PCB. In this
way, double-layer 360.degree. omnidirectional and dead zone-free
shielding of the radio frequency connector can be realized by the
first shielding layer and the second shielding layer, and a better
enclosed environment is created for the first terminal and the
second terminal.
[0036] Referring to FIG. 2 and FIG. 4, to reduce the installation
space of the radio frequency connector, the first shielding frame 5
has convex encapsulation parts 6 for covering the weld legs of the
first terminal 3, and gaps are reserved between the inner walls of
the convex encapsulation parts 6 and the weld legs of the first
terminal 3. Similarly, the second shielding frame 7 also has convex
encapsulation parts 6.
[0037] Optionally, the first shielding frame 5 is directly
conductive with the second shielding frame 7 in the manner of point
contact, surface contact, gaps or the like, or is indirectly
conductive with the second shielding frame 7 by means of a
conducting part or the like. A better enclosed environment can be
created by the conduction of the first shielding frame and the
second shielding frame.
[0038] According to the radio frequency connector provided by the
invention, the complete and gapless shielding frames are disposed
around the bases to realize 360.degree. omnidirectional and dead
zone-free shielding of the radio frequency connector, so that the
anti-interference performance (shielding performance) of the radio
frequency connector is effectively improved, and the electrical
performance of the radio frequency connector is improved,
accordingly.
[0039] The above embodiments are merely illustrative ones of the
invention, and are not intended to limit the patent scope of the
invention. All equivalent transformations made on the basis of the
contents of the specification and accompanying drawings, or direct
or indirect applications to relating technical fields should also
fall within the patent protection scope of the invention.
